Title: Apparatus for seaming pieces of textile fabric or the like
IPC: D05B27/06
Filed: 1974-08-02
Abstract: 1470678 Longitudinal registering of webs STAHL-URBAN CO 2 Aug 1974 [3 Aug 1973] 34216/74 Heading B8B [Also in Divisions D1 H2 and G3] Apparatus for seaming two pieces of material A, B comprises a sewing machine, feed devices 7, 9 for the respective pieces of which the device 7 can be varied in speed relative to the device 9, sensor units 105, 107 for detecting an out-ofregistration condition between the trailing ends of the pieces and control circuitry responsive to the sensor units and adapted to control the speed of device 7 to return the piece ends into registration at the sewing machine. The device 7 comprises a dog whose throw is determined by the amplitude of an oscillating shaft 49 which in turn can be adjusted by raising or lowering a rack 67 by means of a stepping motor 77. The circuitry includes a section 201 responsive to a LED5 and phototransistor Q5 to set the speed of the device 7 initially equal to that of the device 9. When the trailing ends of pieces A, B pass sensor unit 105, the degree and direction of correction required of the motor 77 are determined by LEDs 1 and 2 and phototransistors Q 1 , Q 2 . The necessary number of steps of the motor-A count on counter 237, accumulated from an oscillator 235-is compared at 239 with the actual number of steps of the motor-B count at 241-and when the counts are equal the motor is stopped. The motor is stepped by flip-flops FF5, FF6 which alternately energize respective halves of each of a pair of windings 265, 267 and can be reversed by a multiplexer M2 controlled by a flip-flop FF7. A C count equal to half the A count is registered at 243 and is compared at 251 with a D count-i.e. the displacement between the piece ends at sensor unit 107. The latter is halfway between unit 105 and the sewing machine, therefore the C and D counts should be the same if the ends are to achieve registration at the machine; otherwise a further correction is applied.

Abstract: 1,003,433. Division circuits. NIHON GENSHIRYOKU KENKYU SHO. Sept. 14, 1962 [Nov. 18, 1961], No. 35217/62. Heading G4G. A division circuit is arranged so that an alternating current proportional to a dividend and a current proportional to a divisor are simultaneously introduced into a logarithmic element (in which the voltage across the element is proportional to the logarithm of the current flowing through the element) and where the arrangement is such that only the component of the output voltage across the element which is at the fundamental frequency of the alternating current representing the dividend is picked up, amplified and demodulated. A current i 1 (t) proportional to a divisor is applied at the terminals 1, 2 of the circuit, while a current or voltage i 2 (t) proportional to a dividend is applied at the terminals 3, 4. The signal i 2 (t) passes to an oscillator and modulator circuit 5, wherein the signal i 2 (t) is used to modulate an alternating signal Io sin #t. The output signal from the modulator is added to the signal i 1 (t) and together they are applied to the logarithmic element 6 which may be a diode or transistor. The voltage across the logarithmic element contains a component whose approximate value is proportional to i 2 (t)/i 1 (t) sin #t provided i 1 (t) is considerably greater than i 2 (t) and this may be filtered out provided that # has been chosen to be much greater than the angular frequencies of either i 1 (t) or i 2 (t). The signal is amplified in unit 7 and filtered and demodulated in unit 8 to give the required quotient signal at the terminals 9, 10.
